Is International Law International? takes the reader on a sweeping tour of the international legal academy to reveal some of the patterns of difference, dominance, and disruption that belie international law’s claim to universality. Both revealing and challenging, confronting and engaging, this book is a must-read for any international lawyer, particularly in a world of shifting geopolitical power. Pulling back the curtain on the “divisible college of international lawyers,” the author shows how international lawyers in different states, regions, and geopolitical groupings are often subject to differences in their incoming influences and outgoing spheres of influence in ways that affect how they understand and approach international law, including with respect to contemporary controversies like Crimea and the South China Sea. Using case studies and visual representations, the author demonstrates how actors and materials from some states and groups have come to dominate certain transnational flows and forums in ways that make them disproportionately influential in constructing the “international”—a point which holds true for Western actors, materials, and approaches in general, and Anglo-American ones in particular. But these patterns are set for disruption. As the world moves past an era of Western dominance and toward greater multipolarity, it is imperative for international lawyers to understand the perspectives of those coming from diverse backgrounds. By taking readers on a comparative tour of different international law academies and textbooks, the author encourages international lawyers to see the world through others’ eyes—an approach that is pressing in a world of rising nationalism.
